Guzdraj denied attacking the then 18-year-old in Rugby town centre but was found guilty of rape and supplying her with class A drugs following a trial.

Guzdraj was handed 16 years behind bars for the rape, with a consecutive two-year term for supplying her with ecstasy, and was ordered to register as a sex offender for life.

Judge Sally Hancox told Guzdraj: “What you did amounts to abduction. Being led to the place where you raped her clearly shows this episode took place over a substantial period.

“I’ve no doubt you saw and recognised her vulnerability. You saw a target, and from that moment on she became your victim.”

Prosecutor Peter Cooper had told the jury the victim, who was 18 at the time of the incident in 2016, suffered from a mental disorder which meant she had an academic age of about 12.

Because of her condition, which was obvious to anyone who met her, she was naive “and inclined to answer questions with an instant yes, without really understanding what she’s expected to do”.

Mr Cooper said: “She would do anything an adult tells her. It would have been apparent she presented as significantly younger than her chronological age, and in a doctor’s opinion she did not have the capacity to consent to sexual relations at the time.”

With the aid of comprehensive CCTV coverage of Rugby town centre, he talked the jury through the girl’s encounter with Guzdraj, beginning as they approached the Asda store from opposite directions at around 8.45am.

“He saw and approached her outside Asda, and there was a brief conversation in which he propositioned her and asked if she wanted sex. She had never seen him before.

“The defendant in his interview would tell the police he accepted he had propositioned her.

“We say it was because he recognised straight away this was someone who was profoundly vulnerable.”

The girl walked away and went into Asda as Guzdraj went back in the direction he had come from, but then turned back and began to talk to her again after she had left the store.

He asked her again if she wanted sex and she told the court she said no, but he persisted and told her to follow him.

“He told her he had a place to go to with a sofa and a coffee table, but this turned out to be a sordid shelter at the back of an abandoned building,” said Mr Cooper.

“It is quite clear he knew she was scared, because on the way he asked her if she was scared of him, and she said yes.”

As they walked, Guzdraj told her to put her hand down his trousers and touch him, and she did as she was told.

But when Guzdraj then went into a shop to buy beer and condoms, leaving her to wait outside, she took the opportunity to make off back into the town centre.

“Sadly it doesn’t end there,” Mr Cooper told the jury.

Guzdraj claimed he decided to go home – but CCTV cameras showed him scouring the town centre, searching for her for more than half an hour before eventually finding her by a bus stop.

He told her to follow him and as he led her away from the town centre and across a car park to the scruffy shelter, he gave her a tablet which she said “tasted like medicine”.

She said he had taken it from a Tic-tac box, telling her “this is my type of Tic-tac”, and although Guzdraj claimed it had been a Tic-tac, Mr Cooper said it was actually an ecstasy tablet.

In the shelter, which was “furnished” with a broken pallet and a polystyrene block as a table, the effects of the tablet hit her and he got her to drink some the beer and try some cannabis, which made her sick.

The court heard that Guzdraj then sexually assaulted her and asked her to undress, to which she said “This isn’t right”, but eventually complied.

He then raped her and afterwards apologised and made her promise not to tell anyone.

After they left, the girl made her way to a coffee bar in the town centre and asked a member of staff to call a Town Ranger.

Guzdraj claimed in court that he had not realised the girl had any form of learning disability, and said she had gone with him willingly.

Judge Hancox also told Guzdraj: “CCTV of your movements showed you approaching the Asda supermarket where you approached her. You were obviously taking the time to look at female members of the public, checking them out.

“She was a stranger to you. Nonetheless within minutes you asked her if she wanted to have sex with you. She was persuaded by your persistent attention to stay with you.

“She followed you, although she expressed her doubts about being with you and her desire to leave.

“You persuaded her to take, and gave her a class A drug, ecstasy. You told her it was your kind of Tic-tac and just to try it.

You knew you were not giving her innocent confectionery.

“You asked her to wait while you went into a shop. She waited a short time and then elected to walk away.

“You and she were apart for 23 minutes. What you were doing during this 23 minutes was hunting for her, and arguably hunting her.

“You had decided you were going to find her and continue with your plan – and you carried out that plan.

“You denied this matter from start to finish. There has been no explanation or contrition.”
